Research and Design of Noise and Vibration Control Device for Substation Equipment

With the development of society, the improvement of people’s living standards, the universal use of universal substation equipment, and the emergence of new types of electromechanical equipment are endless, and there are more and more noise sources in people’s living and working environment. In particular, the vibration caused by the noise of the substation equipment will cause the mechanical equipment parts of the substation to fall off, affecting the working efficiency of the substation equipment, and even causing a short circuit of the substation and causing a major hazard such as a fire. Existing research cannot effectively solve the problem of vibration caused by the noise of substation equipment. This paper introduces HHT denoising model and calculation method to study vibration control. The tracking simulation results of 500 kV substation equipment show that the denoising algorithm can effectively remove the low-frequency interference of the signal according to the background signal characteristics and the algorithm can be adaptively denoised.
